Some cricket writer originally dealt blow (9)
I believe the answer is:
overspend
'blow' is the definition.
(overspending is a kind of blowing)
'some cricket writer originally dealt' is the wordplay.
'some cricket' becomes 'overs' (over is a sequence of deliveries in cricket).
'writer' becomes 'pen' (something which writes).
'originally' indicates taking the first letters.
The first letter of 'dealt' is 'd'.
'overs'+'pen'+'d'='OVERSPEND'
(Other definitions for overspend that I've seen before include "To exceed one's budget" , "Consume too much" , "splurge" , "Use too many resources" , "Buy too much" .)
